SRWare Iron Opens to Black Screen using Sandboxie

[JP1000]

I am using SandBoxie 3.76. When I open SRWare in the sandbox, the browser opens, but all I see is a black screen. This problem doesn't occur when running SRWare Iron outside of the sandbox. All other browsers work, including Chrome. I tried it with SandBoxie 3.74, same problem. I tried using an earlier version of SRWare Iron, same problem. I have a Windows 8 x64-bit machine. This problem doesn't occur in my Windows 7 x64-bit machine.
